HMD Control Module Voice Recognition for Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable Head-Mounted Devices (HMDs) face usability issues due to vibration caused by user input, limited visibility of control buttons, and potential dizziness from movement discrepancies between user and screen movements, which degrade user experience and battery efficiency.
Innovation Solution
An electronic device with an integrated HMD control module that recognizes user inputs, such as gestures and environmental markers, without additional modules, allowing intuitive control and reducing vibration, while tracking user movement to prevent dizziness and optimize battery usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touchpad and physical key button are included in HMD, then user can control electronic device, but user cannot see object ahead and practical use is degraded
Solution Approach 1:
The patent replaces mechanical control interfaces (touchpad, physical buttons) with voice recognition technology. The voice recognizer module detects user commands through audio input, eliminating the need for physical controls that would obstruct the user's field of view. This substitution maintains device control capability while removing the visibility obstruction caused by mechanical components.
2Ease of operation
If touchpad and key button are pressed, then user input is registered, but slight movement occurs causing dizziness
Solution Approach 1:
The patent replaces mechanical input methods with voice recognition, eliminating physical pressing actions that generate vibration. Voice commands are detected through acoustic sensors without requiring physical contact or force application, thus preventing the vibration and movement that would cause user dizziness while maintaining input registration capability.
Solution Approach 2:
The voice recognizer acts as an intermediary between the user and the electronic device. Instead of direct mechanical interaction, the user's voice is captured and processed by the recognition module, which then translates commands into device control actions. This intermediary process eliminates the need for physical contact that causes vibration.
3Volume of moving object
If HMD is made slimmer for portability, then body-fitted design is improved, but control components become more limited
Solution Approach 1:
The patent replaces space-consuming mechanical control components with voice recognition technology. Voice recognition requires minimal hardware (acoustic sensors, processing module) compared to touchpads and physical buttons, enabling the HMD to maintain a slim profile while preserving full control functionality through voice-based interfaces.
